Querying and Modifying Properties of an Object

This article shows you how to query and modify the Attributes of an object. The operation steps are as follows:

Select one or more geometry/Text in the Map, right-click, and select the Properties command.
The Properties panel pops up, showing the Details of Select Objects, including Object Properties, Spatial Info, and Nodes; If the selected object is Text, there will also be Text Info in the Properties Panel. The contents of these four options are described below:
- Object Properties: Object Properties displays all the Property FieldAttributes of the object, that is, the Select Fields of the record in the property table corresponding to the object. Include Field, Field Alias, the type of the field, the value of the field, and whether the field is required.
  - Hide System Fields: This check box sets whether to display or Hide System Fields Attributes in Geometry's Attributes window. Check this box to hide all System Field: Attributes, so that you cannot clearly view Non-System Field: Attributes when there are too many System Field:.
  - Hide Details: This check box is used to set whether or not to display or Hide Details fields in Geometry's property window. The Details field includes information such as Field and Type. Check this box to hide the Attributes of other fields and display only the Field Alias and Field Value fields.
- Spatial Info: used to display the Spatial Info of Select Objects, including type, length, Bounds, etc.
  - Object Type: Displays the type information of the object, that is, whether the object is a point object, a line object, a face object, or another type of object.
  - Length: Displays the geodesic length of the line object.
  - Perimeter: Displays the Geodesic Primeter of the face object.
  - Area: Displays the Geodesic Area of the face object.
  - Bounds: Up, down, left and right are used to display the space Bounds Info of the object, where the up and down values are the two boundaries along the Y-axis direction (i.e. 'Y ='); The left and right values are the two boundaries along the X axis (that is, 'X ='), and the units of the values are the same as the Unit of the Dataset where Select Objects is located.
- Nodes: It is used to display the Nodes of Select Objects, that is, the relevant information of the nodes that constitute the objects. It is mainly displayed in the form of a table.
  - Object Info：
    - Object Type: Displays the type information of the object, that is, whether the object is a point object, a line object, a face object, or another type of object.
    - Total number of subobjects: Displays the number of subobjects that make up Select Objects. A simple object is one child object, and a Compound may contain two or more child objects.
    - Current subobject: The drop-down list of the combo box to the right of it lists all subobjects constituting Select Objects. Select any item in the drop-down list, and the lower table will display the information (coordinate information) of the node of the selected subobject.
    - Total Nodes: The total number of nodes (including all child objects) that make up Select Objects.
  - Nodes: The table area displays the Nodes of the current subobject. Each record corresponds to a node of the subobject. The information content is the coordinate information of the node. The Unit is the same as the Unit of the Dataset where Select Objects is located.
    - Add Node: Adds a new node for the last node of the current child object. The default X and Y coordinates are (0,0). This button is available only when Object Layer is selected as an editable layer.
    - Insert Node: Insert a new node at the currently selected node (the row of the cross mark). The X and Y coordinate values of the new node can be entered in the text box below the list box. This button is available only when Object Layer is selected as an editable layer and there is a selected node in the list box.
    - Delete Node: Deletes the node selected in the list box. This button is available only when Object Layer is selected as an editable layer and there is a selected node in the list box. This button is not available when the number of unselected nodes in the list box is less than number of control points for the object (that is, less than 2 unselected nodes for a line object or less than 3 unselected nodes for a face object).
    - Export Node: All Nodes in the export list are in.csv format. All Nodes are exported by default, and one or more Nodes cannot be selected for export.
- Text Info: If Text is selected in the Map, the Text Info option will be displayed in the Properties Panel, which is mainly used to display and set the Text Style of Text. The set Text Style can be previewed in Map in time.
  - Text: Set the text that requires Set Text Style;
    - subobject: Used to set the subobject in the currently displayed Text.
    - Text Content: Displays and sets the Text Content of the current text sub-object.
    - Rotation Angle: Sets the rotation angle of the Text. If the Apply to Subobject check box is selected, the set angle will be applied to all sub-objects of the current Text.
    - Apply to Subobject: After the Apply to Subobject is selected, all Text Styles in this Page Setup will be applied to all texts in the Dataset.
  - Font: Font displayed. It is used to set and set the font used by Text. The drop-down list of the combo box on the right side of the label control provides rich fonts for users to choose. At the same time, the "Recent Font" grouping is provided to facilitate the selection of Recent Font names. The system supports the quick initial positioning font of the keyboard. For example, if you click the letter "T" on the keyboard, the font beginning with the letter "T" will be displayed in the drop-down list box. Click the combo box drop-down list to the right of the label control to select a font.
  - Font Size: Displays and sets the Font Size of Text. You can either enter a numeric value for Font Size or select the appropriate Font Size from the combo box drop-down list on the right.
  - Font height: Displays and sets the height of the Text font.
  - Text Color: Used to set the text color of Text. Click the color button on the right, and the user can select and set the appropriate color in the pop-up color panel, or click "Other colors …" at the bottom of the color panel. Button to customize the desired text color in the pop-up Color dialog box.
  - Background: Used to set the background or outline color of Text. Click the color button on the right, and the user can select and set the appropriate color in the pop-up color panel, or click "Other colors …" at the bottom of the color panel. Button to customize the desired color in the pop-up Color dialog box.
  - Font Effects: Select the corresponding Font Effects check box to apply the Font Effects.
    - Bold: Used to control whether the font of Text is bold or not.
    - Strikethrough: Used to control whether the text is decorated with strikethrough.
    - Shadow: Used to control whether the text of Text has shadow decoration.
    - Underline: Used to control whether the text of Text is decorated with an underline.
    - Outline: Used to control whether the text of Text has outline decoration.
    - Background Transparency: Used to control whether the background of Text is transparent.
    - Left Italic/Right Italic: Used to control the left or right slant of Text.
    - Fixed Size: It is used to control whether Text is Fixed Size. If this check box is checked, it means that the text size will not change with the scaling of the map; if this check box is not checked, it means that the text size will scale with the scaling of the map.
    - Alignment: Displays and sets the alignment of the text in Text. The system provides four types of text alignments: left alignment, right alignment, center alignment, and both ends alignment.
If multiple objects are selected, the tree node above the Properties Panel will display all Select Objects in the current Map. You can select the tree nodes of different objects and switch to view their Attributes. You can make Batch Settings and modifications to the properties of multiple objects in the pop-up Tabular.
